Why does the car make a buzzing sound when turning?
4 Answers
The reasons for the buzzing sound when the car is turning: 1. Insufficient lubrication in the steering column, leading to high friction; 2. Check if the power steering fluid is low; 3. Inspect if there is an issue with the universal joint; 4. The rubber bushings of the suspension stabilizer bar links may have aged and hardened; 5. The wheel bearing may be damaged. Correct methods for steering: 1. After the vehicle comes to a stop, return the steering wheel to the center position to avoid putting stress on the suspension system and tires; 2. When making a U-turn, try to avoid turning the steering wheel to the extreme position; 3. Avoid turning the steering wheel while the vehicle is stationary; try to steer only after the vehicle starts moving. Turning the steering wheel while stationary should only be used occasionally in special circumstances, such as when maneuvering out of a tight spot.
I've been driving for decades and often hear people mention the issue of squeaking sounds when turning. It's mainly a problem with the power steering system, such as the friction noise from an aging or loose belt slipping. For hydraulic power steering vehicles, the belt is connected to the power steering pump. Over time, it can harden or wear out, causing squeaking. If the power steering fluid is too low and lacks sufficient lubrication, it can also struggle to build pressure and produce noise. Electric power steering vehicles normally have a humming sound, but a squeaking noise is unusual and might indicate poor electrical contact. Don't underestimate it—over time, the steering can become heavier, making highway driving dangerous. I suggest first stopping the car, popping the hood, and checking the belt's condition for any cracks. If the power steering fluid level is low, top it up with the same type of fluid. During regular maintenance, ask the mechanic to tighten the belt and adjust its tension. Replacing it with a new part usually solves the problem. Make it a habit to inspect it yourself every month to extend the lifespan of the components and ensure safe driving.
Young car enthusiasts enjoy DIY projects, and I've also encountered the issue of a squealing sound when turning. It's mostly caused by a loose or worn power steering pump belt creating friction, resulting in a harsh noise. Low or dirty hydraulic fluid making it hard to pressurize can also cause the same problem. Checking is simple: start the engine and turn the steering wheel while idling, then use a wrench to adjust the belt tension; use a dipstick to measure the power steering fluid level, and top it up with new fluid if it's low. You can buy a belt online for a few dozen bucks and replace it yourself, but be careful not to overtighten it and damage the bearings. Worn bearings can also cause squealing and require professional replacement. Electric power steering systems rarely have this issue, but if the motor has problems, it's more troublesome. Address any issues early and don't wait until the steering fails—safety comes first for more fun.
I drive to work every day, and the most annoying thing is the squeaking sound when turning. It's mostly due to issues with the power steering belt, like aging or loosening, which causes friction noise. Although the sound is small, the hidden danger is significant, and it's easy to ignore, leading to difficulty in steering and potential accidents. I check the belt in the engine compartment myself—it should be smooth and free of cracks, and the hydraulic power steering fluid level should be above the marked line with a clear color. The issue is more noticeable during cold starts in winter when the oil is thick and lubrication is poor. Avoid sharp turns and sudden steering to reduce wear. During maintenance, specifically ask the repair shop to check the system and add some lubricating oil for prevention. This problem often occurs in older cars, so regular maintenance can save a lot of hassle.
